If Kaguya is now the main villain and Madara isn't fully dead he is going to see who Kaguya really is and try to take out Kaguya in the end sort of how most of the villains in Naruto do like Nagato it's a rough theory of mine but comment what you think
I was just wondering what Sasuke's Rinnegan is all about and maybe some of you guys can post some ideas about what he will use it for in the future. Thanks
